Unfortunately for any children present, it seems that when Spider-Man saw the famous 'I Want You!' recruiting poster featuring Uncle Sam, he took it literally.
The window washers at Le Bonheur Children's Hospital in Memphis, TN, kind of make 'Patch Adams' seem like a big old meany. Two of the hospital's three-man window washing team dressed up like Spider-Man, and then rappelled down the side of the building, lifting childrens' spirits while cleaning windows. But yeah, a clown nose is good too.
